Abstract (en)
[origin: WO0148387A1] The present invention relates to a mobile handling device with a hydraulic circuit, which hydraulic circuit (L) comprises a lifting cylinder (1) arranged in a lifting device (100) suitable for handling a variable load and an accumulator (6) for recovering or recycling lowering load energy, the hydraulic circuit also comprising a variable hydraulic machine (3) with two ports (10, 11), which hydraulic machine is capable via a drice unit (D) of emitting full system pressure in two flow directions to said ports, one port (11) being connected to said accumulator (6) and the other port being connected to said lifting cylinder (1). The device is characterised in that the hydraulic circuit (L) comprises a first stop valve (2) arranged in the line between one port (10) of the hydraulic motor and the lifting cylinder (1), and a second stop valve (5) arranged in the line between the hydraulic motor's second port (11) and the accumulator (6), and that the hydraulic circuit (L) comprises a second accumulator (20), which is connected via at least one non-return valve (31) to the line between the hydraulic machine (3) and the lifting cylinder (1).
